도파민은 홍합 모방물질로 표면개질 가능한 표면의 다양성과 편리한 개질 방법으로 인해 여러 분야에서 각광받고 있다. 본 연구에서는 이러한 도파민 표면개질 방법을 최적화 시켜 수분 안에 기존의 특성에 변화를 주지 않고 표면개질이 가능 하도록 개선시켰다.

A simple and rapid capillary electrophoresis method was developed for the quantitative analysis of common triazine herbicides. Cyclic voltammetry was employed to clarify the detection voltage which showed characteristic irreversible cathodic peaks. For the analysis, the mixture of triazine herbicides was applied in a microfluidic chip to determine the CE-separated peaks. Soil sample extracts were analyzed directly after drying and redissolution with the supporting electrolyte but without other pretreatment. The results were comparable to those obtained by HPLC with UV detection. Therefore, this method can be used in the rapid determination of pesticide/herbicide residues.

Tunnel field-effect transistor (TFET) is a promising candidate for the next-generation electron device. However, technical issues remain for their practical application: poor current drivability, shor-tchannel effect and ambipolar behavior. We propose herein a novel recessed-channel TFET (RTFET) with the asymmetric source and drain. The specific design parameters are determined by technology computer-aided design (TCAD) simulation for high on-current and low S. The designed RTFET provides ${\sim}446{\times}$ higher on-current than a conventional planar TFET. And, its average value of the S is 63 mV/dec.

We investigated photo-induced electron transfer (PET) in a dye-labeled peptide, fluorophore-Ala-Gly-Gln-Tyr, employing time-resolved fluorescence. As an effort to develop new functional dyes, we studied an acriflavine derivative for the electron-acceptor in the excited state from tyrosine, an electrondonor in the ground-state. The pH dependence of the fluorescence lifetime of the model peptide indicates that electron transfer between the excited dye and tyrosine occurs when the tyrosine is deprotonated. The proton-coupled electron transfer appears to be sequential rather than concerted. We also report direct time measurements on the end-to-end loop formation processes of the peptide in water.
